Hello all.

I want to get my dpf removed from my car as it would save me a hell of a lot of cash when clogs or needs changing
And what have you. But I need some help.
Has anyone had there's removed on a focus?
Has there been any difference in power? Or economy?
How much would it roughly be for a removal. And would they just take the filter out and leave the case there so it won't look like anything has been done.
Would it be an mot failure ive heard it is and it isn't?

My car is still under warranty but I'd like to get it chipped ie bluefin and to get best results would be to get rid of that crap filter.

Hope someone out there has done it.

By the way I have a 1.6tdci 110

Many thanks

1st of all removal of the DPF should not cause your car to fail a UK MOT -

Unless the exhaust produces exessive smoke (if its done right it shouldent)

A phisical DPF removal, with an electronic DPF removal can be done as part of a remap, and somr tuners do the complete hat-trick, im quite a Superchips Bluefin fan, but im not sure they actually do electronic DPF removal with a Bluefin.

I don't run a 1.6 Focus with a DPF, or had one done, but

I agree your better off without a DPF, you are liable to get better performance, economy etc

Thanks for your reply

Yeah that's what I thought because only petrol cars need to have a cat otherwise it will fail mot and not pass emission buta diesel can according to vosa? My car doesn't smoke but only when the dpf regens. But what's the point in it. All it does is gather soot and then at some point burns it off making a nice big soot cloud. Hardly Eco friendly lol. I would love to get it done but the car still has another year warranty but in that year the dpf could fail and ford knowing what they are like would not cover That as itit's a consumable item. But yeah my car is good drive but still got flat spots and I've also heard to blank off the egr valve as that can eliminate or at least help it. But again mot thing. But like you say get the correct map and it should pass.

How much do you think it would cost? As a rough idea?

Cheers

mate if i were you,i wouldnt get it chipped. ive had 4 cars remapped & in the end they ALL smoke like hell. I've found that 110 turbos aint the best for remapping at the best of times.AND your clutch will fail.every one of mines failed within a month within remapping them. And Im 47 and no boy racer so am kind to my cars and dont rag em. If your cars not worth much then by all means go for it,but if its worth a few grand i wouldnt if i were you

Ballpark about £250- £650

If you get a remap from a top, well established tuner, and you feel there is a bit too much smoke, they will often modify the remap free-of-charge untill you are happy with the amount of smoke coming out the back

Often having a DPF just collects the soot in normal driving and then dumps it out all-at-once when you "boot" the car - not having a DPF will help here

Some people say "no smoke - no poke :lol: " and love to leave other cars in a diesel-y smookescreen - others hate to see any smoke coming out the back - its a personal thing - (as long as it passes the MOT)

Personally i would wait untill it was out of warranty before modifications like that - (let the garage pay for repairs/ sort it)

If they refuse - then ditch the DPF/ get a remap etc

I can't see you getting enough power/ torque out of the 1.6 to really "scare" the clutch/ dpf, - im putting out about 400Nm/180Hp in my Mondeo, ive upgraded to a soiid flywheel, (the DMFs can be a bit "soft" if you are "kicking out" a lot of torque at low revs)& carbon/ kavlar clutch - ive had no problems - 100% reliable

A "progressive" map (with a staady rise in power/ torque) can put less stress on the DMF/ clutch/ transmission

there are good & bad remaps - just like anything else

I think youre a brave man. I would NOT put any SMF into a car that originally had a DMF thats been remapped. Mondy's etc might be different, & i hope so anyway cos i put smf's into 2 passats & 1 golf that came with dmf's and they all ended up the same-knackered!
There was Insufficient dampening due to no dampners cos of smf,and main shafts 'end-up' shook to bits. Theres a lot of info just starting to appear on forums due to this mod. Please look and read up on it. A lot of technicians are starting to say the same thing. They also say the design of the dmf was t great to begin with but it handled the vibrations etc to a better extent, than any smf.
Lot of taxi drivers are also finding out the hard way,especially vw and ford drivers. Im going to the top guy in scotland tomorrow & im gonna be asking him about this then I'll get back n let ya's know if u want.Im not specifically going there to ask about smf/dmf lol but its something ive wanted to ask a transmission expert(this man's the type o guy thats too busy wi clutch/box probs,to answer things for nowt online) Who knows,i could be proved wrong

4 smoking remaps, 4 broken SMFs DMFs within a month? You don't seem to have much luck with cars! (or you must be doing something very wrong) unless this is a "wind up"? LOL


The original streetperformance 2.2 Mondeo had a solid flywheel conversion - this was used for drag racibg speed tests, racing rond the Norchcliff?

the 300Hp ST220 running ITBs featured in "Fast Ford" magazine has a solid flywheel conversion

There was £1000s spent on these cars and the modifiers/ tuners know what they are doing, they fitted SMFs/ solid flywheels for a reason
The DMF would not have handled the torque

Ford supplied a version of the MK3 TDDI 2.0L with a solid flywheel

Ford offered a solid flywheel conversion on some Transits (so some SMFs are genuine Ford parts)

A solid flywheel is just that - a solid plate with no moving parts - nothing to go wrong

It can have a more "direct" feel with less give in it - a sprung plate helps to put this "give" back in the transmission after fitting one

All the above is fact/ and/ or based on my own experiences -

A load of rubbish can be written on the internet and passed down as "fact"
Anything done wrong can have problems - DPF removal, SMF conversions, remaps etc - and repairs on cars

I fitted my solid flywheel 2 years ago - the clutch did not explode, the crank did not break - it has worked perfectly - if i had reffited a DMF, it may have failed by now (due to the extra low-down torque, that tends to "chew up" DMFs)

As far as im aware i run the most heavily modified Mk3 Mondeo diesel , its kiching out about 400Nm of torque at 2.2k, so on an upchange the revs can fall into ths torque band, - a DMF would not last long (the original one didn't)

The SMF is a solid plate so no moving parts to go wrong, it is dynamically balanced and matched to the other transmission components - the pressure plate is a heavy-duty (much stronger than stock) matched to the flywheel, it has a 30% stronger clamping force (this is to prevent the clutch slipping with all that power/ torque) - the driven plate has a heavy- duty bearing, it has a sprung plate built in to it, (to replace the "give"in the trans missing from the DMF ) the actual friction material is carbon fiber and kevlar (very strong)

The same type of clutch is used (as an upgrade!) in EVOs, Subarus and racing Porches (400Hp- 800Hp) so if its good enough for them......

i will start another thread about SMFs DMFs carbon clutches etc

Jesus! Sounds like ts not such a good idea after all. I have been giving a few months of thoughts. Just wanted to try and save money in the long run for when the dpf does fail as I don't seem to have much luck.

I think I may stick to a green cotton filter then as that seems to do wonders :)

See my car is a lease scheme and I was thinking about changing the car to the new focus but I do a good few miles and want a diesel so I could tune it and make it better on fuel.

Maybe petrol seems to be the way forward. My girlfriend is taking ownership of the new shape ford fiesta with the new ecoboost engine. In frost white. Can't wait :)

I new clutches would be a problem but I thought that only if you always boot the car you'd get problems?

Thanks for all your help.

Maybe petrol ecoboost. I'll find out today what I can do and let you know

Cheers guys

ok.where are you getting a month from? Mate I'm on about over a period of 9 years.
I'm not on about 2.2's. Im on about 2.0's
Anyway.I'm just back from Ford. Spoke to the head guy there,& he reckons the same. They're getting calls from dozens of folk (taxi drivers AND boy-racers),and theres a huge amount of damage getting done to the main-shaft bearings inside the box due to SMF conversion ALONGSIDE A REMAP.. He said some of the faults could be caused by incorrect alignment of clutch etc,BUT there are more and more cases coming to light from folk who've remapped the car AND fitted a SMF conversion. His advice:- " Dont chance it if your cars mean a lot to you". At the same time he said "plenty of boxes 2nd hand if need arises" but its a gamble. Now this guy-all he does is fix transmissions on fords. He's the 2nd person Ive heard say bad things about this. The 1st was a VW transmission specialist. I know you'll not change mate, and thats ok. But theres too many folk saying to get this done & that done as modifications etc,and internets full of the results gone bad. Have you done a search on this,or are you basing your comments on just your own cars? Im on about guys that're fixing these problems 7 days a week,8 hrs a day.Cant really ignore their advice. And the springs on the clutch are NOT enough to dampen the forces.Nothing near it. Do you feel the vib's through the clutch pedal?

From you - you said in post no. 4 on this thread "your clutch will fail.every one of mines failed within a month within remapping them."

The internet is full of lies, nonsense, misinformation, im sure if i looked hard enough online i could find compelling evidence that the moon is made of cheese! - its just someones theories/ opinions - the chap i bought the SMF from also sells DMFs and recommonded the solid flywheel - i run one personally - its not second- hand information or some nonsense someone has written

the clutch is very smooth

I dont mean ALL in the 1 month.And whats clutch failing got to do with DMF/SMF issues? When I said that,all I meant was "Be prepared to fit a clutch after your remap,cos the extra torque will make it slip eventually,unless your clutch is pretty damn good to begin with. Look mate-aint gonna argue with you.been there done it,got tshirt,& was expensive. So if I sold you a cheese roll,& recomended that instead o cheese,you used the cheese off my ,ya'd say "wow yes please". Time will tell. I'll bet you,that this will happen MORE & more,cos lots are trying SMF & remaps nowadays. I'm trying to pass-on whats happened to me,AND others. The only difference wi them & us is that they have better things to do,than drone on about it online.Watch this space.You'll see. Now instead off firing back with some answer straight away,wait n see if anyone is prepared to back up what ive said. Granted,its not the busiest forum but I guarantee you'll hear lots of this in the near future. Dont say I never warned you though. .
Here's an idea. IF there was a way I could bet you money tonight,that in say 4 years,its known widespread all accross uk that a performance remap,plus SMF conversion is NOT good for cars,Id put money on it. Thats how sure & confident I am of this
Just realised I forgot this. I'm not saying SMF's are ,but what i AM saying is dont performance remap your car alongside one at same time.By all means,if you've got meatier gearbox etc,then go ahead,but not with the stock ones. Think about it,Ford etc spend gazillions on testing the limits of these things,They're meant for only a certain tolerence. Ramp up the torque,you have more forces at work. Theyre not designed for it. Its the same with VW Gt tdi 140's.There are folk who've caused major damage thinkin they'd remap/smf their cars,and £2k bill later,theyve found out the hard way. Mazda have turned & said they dont reccomend ANY DMF's in some of their cars due to vibration etc.A couple of other manufactureres have also said same thing. Honestly guys,stop bein sheep

Gentlemen, please, lets play nicely :)

Remember, we are a community here and we will all have different opinions, but that does not mean that we cant have a difference in opinion without getting aggitated at each other.

now, if we can restore tranquility to the thread, please do continue, difference of opinions are always going to be there, and just because someone disagrees, doesnt mean we need to get aggrieved at the comments.
